Hi,
I am looking for the following paper.
Theory of representations for tensor functions - A unified invariant approach to constitutive equations - Q -S Zheng, Applied Mechanics Reviews, 47(11), 545-587, 1994.
If anyone has this paper, I request you to share.
Thanking you,
Best regards,

Hi all,
I am thinking that it is a good idea to have 'iMechanica' smart phone app (like facebook, twitter etc). We can post/check blogs using a smart phone. I request moderators and imechanicians to comment on this.

Hi all,
I was going through Constitutive Modeling in Continuum Mechanics. I came across the Transversely Isotropic Materials (TIM). I have a couple of doubts, which are listed in the attached pdf file. I request the Continuum Mechanicians to clarify.
Thank you in advance,
Best regards,

Hi all,
I am looking for ANSYS-LSDYNA tutorials. If anybody has, I request him/her to kindly share or post the links.
Thanking you,

Hi all,
When we do a non-linear buckling analysis, initially we introduce some imperfections (mode shapes of mode 1, 2 etc) from eigen buckling analysis. Then we multiply the load with eigenvalue of the first mode. This load is applied on the structure having imperfections. Now put on non-linear geometric option and run the analysis. At bifurcation point we get non-linear buckling load. Non-linear buckling load comes close to eigen buckling value.
Decription of my problem is as follows.
Hi all,
I have attached a single slide ppt file with this blog. In this slide, there is a hollow cylinder subjected to internal pressure and non-uniform axial load. All the translations at the bottom of the cylinder are fixed. As a whole the cylinder is subjected to a complex loading. The cylinder is modeled using SHELL elements in ANSYS. Now I know how to carry out non-linear buckling analysis in ANSYS.
Hi all,
I have a doubt as follows.
"Why stress based Finite Element Analysis / Method is not popular compared to displacement based FE?"
I request you those who has some idea about this to comment.

Hi all!!!
In Finite Element Method (FEM), Hermite interpolation functions are used for interpolation of dependent variable and its derivative.
In FEM books, Hermite interpolation functions are directly written in terms of Lagrange interpolation functions. No derivations are given. I searched in Numerical methods books also for derivation of Hermite interpolation functions. I couldn't find.
I am looking for the origin (basically the derivation) of Hermite interpolation functions. Kindly help me.
Thanx in advance and regards,

In imechanica when a blog is posted, we get good response / discussion (or sharing ideas, knowledge etc) from members. This happens many times.
If there is no response for a particular blog even after many days...then....what? It may be updated (because some members might have missed it). Even then also if there is no response, what may be done???
